RAILWAY-FASTENIN G.

Original application filed May 16, 1908, Serial No. 433,243.

Specification of Letters Patent.

Serial No. 461,403.

To all whom it may concern:

Be it known that I, CHARLES H. CORNELL, a citizen of the United States, residing` at Valentine, in the county of Cherry and State of Nebras ta, have invented certain new and useful improvements in Railway- Fastenings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to rail fastenings for railway tracks, and is a divisional application upon my original application tiled May io, 190s, sei-iai No. 433,243.

It has for its object to provide an improved fastening which is inexpensive and may be quickly adjusted because it does not require the use of screws, spikes or rivets.

Another object is to provide a fastening' bolt which may be adjusted to have the proper clamping action and locked at that point even though the proper clanipingz,` point on any two bolts should not be the same.

Further objects of the invention will become apparent from the following` description.

It is obvious that the construction of bolt illustrated and described herein as applied to railway rails and ties may also be used for securing parts of other metal construction work such as steel framework for fireproof buildings, steel bridgework, viaducts, etc.

The invention contemplates the use of integral bolts provided with laterally eX- tending lugs formed at their lower ends and heads adapted to clamp upon a part to be fastened. The shanks of the bolts with their lugs are passed through key slots with said lugs engaging the under face of the part in which the slots are formed. if said under face is beveled, the turning of the bolts with their lugs riding upon said beveled surface, will give the desired clamping action. lVhere the lower face of the slotted part is not beveled, I provide the heads of the bolts with spiral cam-shaped under faces which produce the desired clamping effect when said bolts are turned. It will be understood, of course, that the spiral cam-shaped heads may be used when the surface of the slotted part engaged by the lugs is also beveled, the result being,` that the clamping action is obltained by turning;` the bolts a much less de- `grec than is required when either the lower i face of the slotted part is not beveled or the under faces of the heads are not cani-shaped.

The invention consists further in the features of construction and combinations of parts hereinafter described and specified in the claims.

In the accompanying drawings, illustrating the preferred embodiment of my inven- `tion: Figure 1 is a broken side view of a tie and yail fastened together with a bolt provided with a series of notches in the edge `of its head through which a locking pin is iinserted into the extension of the key slot iin the tie. Fig. 2 is a plan view thereof. j Fig. 3 is a vertical section taken through the key slot.

Referring more particularly to the drawings, the upper flange of an eye beam tie l, of the usual construction, is provided with `key slots 2 through which are passed the shanks 3 and radially projecting` lugs i of the fastening bolts 5. The head 6 of each bolt is adapted to engage and clamp upon the foot of the rail 7. The under faces of said heads may be spirally cam-shaped as at 8. The head of the bolt is provided with a series of radial notches 9 through one of which the locking pin l() may be inserted into the extension of the key slot- 2. Because of the repetition of the notches at intervals in the head, one of them will always be in alinement with the extension of the key slot when the bolt is set in clamping` position.

A washer 12 may be interposed between the foot of the rail and the head of the bolt, if desired, te fill in any adjustments intermediate of the notches or to take up wear. For this purpose the washers `employed may be of different thicknesses. rihe bolts may be made of any suitable substance such as wood, vulcanized rubber, papieranach or like materials which will deaden sound, the latter being particularly adapted for use on elevated railways.

I claim:

l. The combination, with a part having a key slot therein, of another part to be secured thereto, and a bolt comprising a shank with a lug on its end adapted to be passed through said slot and engage the face of the first mentioned part when the bolt is turned, a head on said bolt adapted to engage and clamp upon the second pa.rt,-said head having a series of radial notches therein, and a pin adapted to engage one of said notches and the extension ot' the key slot for the purpose specified.

2. The combination, with a part having a key slot therein, of another part to be secured thereto, and a bolt comprising a shank with a lug on its end adapted to be passed through said slot and engage the tace of the lirst mentioned part When the bolt is turned, a head on said bolt provided with a spiral cam-shaped under face adapted to engage and clamp upon the second part, said head having a series of radial notches therein, and a pin adapted to engage one of said notches and the extension of the key slot ifor the purpose specified.

The combination, with a part having a beveled tace and a key slot therein, of another part to be secured thereto, a bolt comprising a shank With a laterally extending lug at its end adapted to be passed through said slot and engage the beveled face of the first, .mentioned part, and a head adapted to enga ge and clamp upon the second part, said head having a series of radial notches therein, and a pin adapted to engage one of said notches and the extension of the key slot for the purpose specified.

4t. The combination, with a tie having a key slot therein, ot a .rail, and a bolt comprising a shank With a lug on its end adapted to be passed through said slot and engage the under tace ot the tie when the bolt is turned, a head on said bolt adapted to e11- gage and clamp upon the foot of the rail, said head having a series of radial notches therein, and a pin adapted to engage one of said notches and the extension of the key 1 slotl tor the purpose speeilied.

The combination, with a tie having a key slot therein, of a rail, and a bolt coinprising a shank vwith a lug on its end adapted to be passed through said slot and engage the under tace of the tie when the bolt is turned, a head on said bolt provided With a spiral cam-shaped under face adapt-ed to engage and clamp upon the foot of the rail, said head having' a series of radial notches therein, and a pin adapted to engage one ot' said notches and the extension ot the key slotfor the purpose specilied.

(l. The combination, With a tie having a beveled under tace and a key slot therein, of a rail, a bolt comprising a shank with a laterally extending lug at its end adapted to be passed through said slot and engage the under tace of the tie, and a head adapted to engage and clam p upon the foot ot the rail, said head having a series of radial notches therein, and a pin adapted to engage one ot said notches and the extension of the key slot tor the purpose specihed.

In testimony whereof I altix my signature, in presence of tivo Witnesses.
